while it doesnt work as fast on pimples as the pimple cream my dermatologist prescribed to me (obviously, since that's medicine and much stronger), it's great to use in the day ( i cant use my pimple cream in the day under sunscreen and/or makeup) not obvious at all (at least for my fair skin tone) and works pretty well. only bought one sheet to try but running out very soon. will be purchasing more (and multiple!)
